That's not to say other space agencies aren't eying the enigmatic moon. The European Space Agency is currently planning the Jupiter Icy Moon Explorer, or JUICE, mission for a 2022 launch. The spacecraft will carry out flybys of Ganymede, Callisto and Europa, but as noted by SPACE.com's Mike Wall, JUICE will only fly past Europa twice.
Flybys are all well and good, but until we physically land a robotic mission onto Europa's surface, returning photographs of stunning landscapes of dirty ice, we'll never fully appreciate the life-giving potential Europa appears to possess.
